You can use timer to know the battery discharge. You don't need altitude, because you can see it. You don't need arrow home, cos you can use a flare gun. You actually even don't need RTH, just fly around yourself.

I have conditions, when RTH is not acceptable. Flying low, or between the trees. Or whatever... Not everybody fly your style.

Numerous reasons
Last known position in case of a crash
Pure interest (it is a hobby after all isn't it)
Staying level in the clouds (built in gyros and/or artificial horizon)
Home pointer, I get lost easily up there
Battery condition/useage information
Oh and of course built in RTH in case I lose radio signal strength

Bottom line is that I preer to fly my planes myself ratehr than have an autopilot run missions for me but I also wnat the built in safety features of a reliable RTH system and the information it can provide via OSD

No you cannot, not accurately and on longer flights not even close

Now someone is just being silly aren't they

If you really really MUST have RSSI then go and buy a system that has that

Seems to me that someone who prefers to fly tight amongst the trees and therefore doesn't need RTH or autopliot due to the obvious hazards is probably just in a thread about an autopilot system with rth to complain just for the sake of complaining

It should work fine, it's radio waves remember so don't allow it to be blocked by metal, try to make sure there are no wires above it etc
I have one of mine inside the fuselage and it has no trouble at all (not an Arkbird mind you)

Thanks for the replies. Mine still on test bench, video flickering when I plug in the fat shark camera. I hava try both pal and NTSC on arkbird with no luck. My set up are Fpv raptor with Turnigy plush 40a esc, orangerx 6 channel full failsave receiver (going to use orangerx lrs soon when I upgrade the firmware) for my ground station I have 7"LCD,immersionRc UNO video receiver, VCR comming soon. And fat shark predator rtf with camera. Going to try other camera that is 12v......any ideas welcome. Thanks
